N2 - In recent years, wireless power transfer has been attracting attention as a means of improving quality of life. In particular, Wireless Power Transfer to electric vehicles is important as part of efforts to solve environmental problems because it contributes to the widespread adoption of electric vehicles. Since electric vehicles need to be recharged more frequently than conventional gasoline-powered vehicles, there are problems such as charging while parked is not enough to cover a sufficient distance, and there is not enough space to install a lot of charging station. Therefore, wireless power transfer to running electric vehicles (DWPT) is important. In this study, the method, which can visualize the compatibility is proposed. The compatibility is visualized by mapping the transfer power and efficiency corresponding to the positional relationship between the transmitting and receiving coils in a DWPT system. Proposed method can be applied not only to sine waves, but also to square waves, which are closer to the real environment. By using this method changes in those coils' positions can be taken considered easily when designing a WPT system. The proposed method is demonstrated by experiments.
